Abstract
tert-Butyl (5-chloropenta-2,4-diyn-1-yl)carbamate and tert-butyl (5-iodopenta-2,4-diyn-1-yl)carbamate are new members of the isostructural family of compounds with the general formula BocNHCH2CCCCX (X = H, Cl, Br, I). In the crystals of all these diacetylenes, molecules are linked via a bifurcated N—H⋯O hydrogen bond and C—X⋯O halogen bond involving the same carbonyl group.
